Answer:

Between 67 and 103 beats per minute

Step-by-step explanation:

The minimum would be 80. That means that the minimum sum would have to be 320 among the four numbers.

85+81+87=253

320-253=67 so 67 will be the minimum

now, we should see the maximum. It will be 89 so the sum of the four numbers cannot be anymore than 89*4 which is 356

So, 356-253=103

yay savvas, my favorite

A. between 67 and 103 beats per minute inclusive

Step-by-step explanation:

What I did was I just started from the top and tried out the mean with 69 and saw that that was 80, so that was right. Then I tried 103, and that was 89, so that's obviously the max. So it was pretty simple. I do not know the way you are supposed to do it. That's what I came on here for, but none of the answers anyone but was right..

Explanation:

Answer:

a. 0.158

b. 0.01942

Step-by-step explanation:

For part a we define probability that the randomly selected person is if 65 years or more than that

a.

Probability of under age = 22.8% = 0.228

Probability of those from age 18 to 64 = 61.4% = 0.614

1-0.228-0.614

= 0.158

b.

P(uninsured) = p(those not up to 18) * p(those uninsured or under 18) + p(those age 18-64) * p(uninsured or under 18) + p(being 64plus) x P(uninsured or 64 plus)

= 0.228 x 0.051 + 0.614 x 0.124 + 0.158 x 0.011

= 0.011628 + 0.076136 + 0.001738

=0.089502

P(65 of older|uninsured) = p(64+) x P(uninsured or 64 plus)

= 0.157 x 0.011/0.089502

= 0.001738/0.089502

= 0.01942

a. The probability that a randomly selected person in the United States is 65 or older is 0.158

b. In the case when the person is  an uninsured American so the probability is 0.01942

a.

Since

Probability of under age = 22.8% = 0.228

And,

Probability of those from age 18 to 64 = 61.4% = 0.614

So, the probabilities of 65 or older is

= 1 - 0.228-0.614

= 0.158

b.

Now

P(uninsured) = p(those not up to 18) × p(those uninsured or under 18) + p(those age 18-64) × p(uninsured or under 18) + p(being 64plus) × P(uninsured or 64 plus)

= 0.228 × 0.051 + 0.614 × 0.124 + 0.158 × 0.011

= 0.011628 + 0.076136 + 0.001738

=0.089502

So,

P(65 of older|uninsured) = p(64+) × P(uninsured or 64 plus)

= 0.157 × 0.011 ÷ 0.089502

= 0.001738 ÷ 0.089502

= 0.01942

Answer:

The probability that neither test is positive

P(A⁻ ∩ B⁻ ) = 0.0108

Step-by-step explanation:

Step(i) :-

Given  the two tests are independently

Test A has probability 0.91 of being positive if the illegal drug has been used

P(A) = 0.91

Test B has probability 0.88 of being positive if the illegal drug has been used

P(B) = 0.88

If   events are independently then ,

[tex]P(A n B) = P(A) P(B)[/tex]

Step(ii):-

The probability that neither test is positive (and thus Al gets to keep his job)

[tex]P(A^{-} n B^{-} ) = P(A^{-} ) P(B^{-} )[/tex]

P(A⁻ ∩ B⁻ ) = P(A⁻ ) P(B⁻ )

                  = ( 1- P(A) ) ( 1 - P(B))

                 =  (1 - 0.91 ) ( 1 - 0.88 )

                = (0.09) (0.12)

               = 0.0108

The probability that neither test is positive

P(A⁻ ∩ B⁻ ) = 0.0108

Answer: y - 5 = -5/6 (x - 18)

Step-by-step explanation:

The point-slope form of a linear equation is written using the slope of the line and one point in the line. From part A, the slope of the line representing this situation is m = -5/6.

Since x represents the number of 10-student groups and y represents the number of 12-student groups, the combination of 18 groups of 10 students and 5 groups of 12 students is represented by the point (18,5).

Question: What is thirty-five and seven thousandths in decimal?

Answer: is 35.007

Answer:

A. 11

Step-by-step explanation:

Since the measure of (4x- 6) is 90°, you would first solve the equation for x

4x - 6 = 90

4x - 6 + 6 = 90 + 6

4x = 96

x = 24°

-------------------------------------------------------------------------------------

Since (4x - 6) was a right angle, (x + 6y) is also a right angle. Therefore, you would do:

x + 6y = 90

24 + 6y = 90

24 + 6y - 24 = 90 -24

6y = 66

y = 11°

The correct answer is 1/2 = ?/100

Step-by-step

The circle is divided into 2 halves and the angle is 100 degrees

Answer:

Step-by-step explanation:

First we need to calculate the sum of interior angle of the pentagon. The sum of interior angle of any polygon is expressed as S = (n-2)180

Given n = 5

S = (5-2)180

S = 3*180

S = 540°

Hence the measure of interior angle of the pentagon is 540°. The sum of all the interior angles will give us;

<A+<B+<C+<D+<E = 540

Given m∠A = m∠D = x°, m∠B = m∠C = (4x)° and the measure of reflex angle at E is (8x)°. If the reflex angle at E is (8x)°, the interior angle at E will be (360-8x)°

Substituting the given values into the formula to  get x;

x+4x+4x+x+360-8x = 540

10x-8x = 540-360

2x = 180

x = 180/2

x = 90°

To find the measure of the reflex angle at vertex E, we will substitute x = 90 into the vertex E = (8x)°.

vertex E  = 8(90)

vertex E  = 720°

The answer is B just took it on ed

Step-by-step explanation:

The statement that correctly describes the graph of f(x) = -x⁴ + 3x³ + 10x² is;

Option B: The graph touches the x-axis at x = 0 and crosses the x-axis at x = 5 and x = -2.

f(x) = -x⁴ + 3x³ + 10x²

At x = 0, we have;

f(0); -(0⁴) + 3(0³) + 10(0²) = 0

This means that the graph will touch the x-axis at x = 0

Answer:

[tex]\sin(\theta)=-\sqrt5/5\text{ and } \csc(\theta)=-\sqrt5\\\cos(\theta)=2\sqrt5/5\text{ and } \sec(\theta)=\sqrt5/2\\\tan(\theta)=-1/2\text{ and } \cot(\theta)=-2[/tex]

Step-by-step explanation:

First, let's determine which quadrant our angle θ lies in.

Remember ASTC, where:

Everything is positive in QI,

Only sine (and cosecant) is positive in QII,

Only tangent (and cotangent) is positive in QIII,

And only cosine (and secant) is positive in QIV.

Since our tangent is negative, and our cosine is positive, this means that our θ must be in QIV.

In QIV, sine is negative, tangent is negative, and cosine is positive.

With that, let's figure out the remaining trig ratios.

We know that:

[tex]\tan(\theta)=-1/2[/tex]

Remember that tangent is the ratio of the opposite side to the adjacent side.

Let's figure out our hypotenuse using the Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

Substitute 1 for a and 2 for b (we can ignore the negative since we're squaring anyways). This yields:

[tex](1)^2+(2)^2=c^2[/tex]

Square:

[tex]1+4=c^2[/tex]

Add:

[tex]c^2=5[/tex]

Take the square root:

[tex]c=\sqrt{5}[/tex]

So, our square root is √5.

So, our three sides are: Opposite=1, Adjacent=2, and Hypotenuse=√5.

Sine and Cosecant:

Remember that:

[tex]\sin(\theta)=opp/hyp[/tex]

Substitute 1 for the opposite and √5 for the hypotenuse. This yields:

[tex]\sin(\theta)=1/\sqrt5[/tex]

Rationalize:

[tex]\sin(\theta)=\sqrt5/5[/tex]

And since our angle is in QIV, we add a negative:

[tex]\sin(\theta)=-\sqrt5/5[/tex]

Cosecant is simply the reciprocal of sine. So:

[tex]\csc(\theta)=-\sqrt5[/tex]

Cosine and Secant:

Remember that:

[tex]\cos(\theta)=adj/hyp[/tex]

Substitute 2 for the adjacent and √5 for the hypotenuse. This yields:

[tex]\cos(\theta)=2/\sqrt5[/tex]

Rationalize:

[tex]\cos(\theta)=2\sqrt5/5[/tex]

Since our angle is in QIV, cosine stays positive.

Secant is the reciprocal of cosine. So:

[tex]\sec(\theta)=\sqrt5/2[/tex]

Tangent and Cotangent:

We were given that:

[tex]\tan(\theta)=-1/2[/tex]

To find cotangent, flip:

[tex]\cot(\theta)=-2[/tex]

And we're done!

Answer:

The probability that the restaurant can accommodate all the customers who do show up is 0.3564.

Step-by-step explanation:

The information provided are:

Let X denote the number of parties that showed up.

The random variable X follows a Binomial distribution with parameters n = 53 and p = 0.96.

As there are only 50 sets available, the restaurant can accommodate all the customers who do show up if and only if 50 or less customers showed up.

Compute the probability that the restaurant can accommodate all the customers who do show up as follows:

[tex]P(X\leq 50)=1-P(X>50)\\=1-P(X=51)-P(X=52)-P(X=53)\\=1-[{53\choose 51}(0.96)^{51}(0.04)^{53-51}]-[{53\choose 52}(0.96)^{52}(0.04)^{53-52}]\\-[{53\choose 53}(0.96)^{53}(0.04)^{53-53}]\\=1-0.27492-0.25377-0.11491\\=0.3564[/tex]

Thus, the probability that the restaurant can accommodate all the customers who do show up is 0.3564.
